What volume of 15 degree celsius water must be added to a 1.2KG piece of stainless steel at 85 degree celsius so that the final temperature is 35 degree celsius. assume the container in which the mixing takes place is perfectly insulated.

Answer 1

[mass H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass steel x specific heat steel x (Tfinal-Tinitial)] = 0
mass H2O is the only unknown, solve for that.
